CEILING R0 SETTE.

Application filed November 12, 1823.

To all whom it may concern:

Be it known that we, WRIGHT BOLTON, Jr., and NORMAN M. PAULL, bothcitizens of the United States, and residents of New Bed ford andFairhaven, both county of Bristol, State of Massachusetts, respectively,have invented an Improvement in Ceiling Rosettes, of which the followingdescription, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

This invention relates to a ceiling rosette for supporting an electriclamp and the object thereof is to provide such a rosette by which thelamp may be resiliently supported to prevent vibration of the lamp andthe breaking of the filament wires.

A further object of the invention is to provide. a ceiling rosette fromwhich an electric lamp may be resiliently supported by the wires whichsupply electricity to the lamp.

Other objects and features of the invention will more fully appear fromthe following description and the accompanying drawings and will beparticularly pointed out in the claims.

The drawings illustrate both in section and elevation a preferred formof construction adapted for use in a ceiling rosette and embody thebroad principles of the invention.

In the drawings:

Fig. 1 is a sectional View of the rosette showing in elevation anelectric lamp supported therefrom I Fig. 2 is an elevdtion showing thebottom of the rosette;

Fig. 3 is an elevation of the insulating sleeve.

The rosette which forms the. subject matter of the present inventioncomprises an apertured boss 1, an insulating sleeve 2 within theaperture and resilient means 8 engaging the boss and supporting thesleeve. The electric lamp lis ipported from the sleeve 2 by means of thewires 5 which supply electricity to the lamp.

The boss 1 is made with a flange 6 projecting therefrom by means ofwhich the boss may be fastened to the ceiling. This flange is providedwith screw openings 7 to permit the screws which fasten the rosette tothe ceiling to pass through the flange. The openings are preferably ovalin shape Serial No. 674,122.

as shown in Fig. 2 in order that the screws may be placed at differentdistances from the center of the rosette thus insuring that the screwsmay be made to engage a lath in the ceiling. The aperture 8 of the bossis of such a size that it will house the insulating sleeve and theresilient means which supports the sleeve and permit movement of the.sleeve within the aperture.

The insulating sleeve may be made of any suitable insulating materialbutl is preferahly of pressed and hardened paper. The sleeve comprisesan elongated shell 9 which projects downwardly beyond the lower end ofthe boss to prevent chafing of the wires 5, and an enlarged head 10 tofit and move within the aperture. The head has a chamber it whichcommunicates with the interior of the shell and within this chamber is aknot 12 formed of the twisted wires 5 which convey electricity to andsupport the lamp. The knot is of such a size that it will lie withinthe. chamber and will not pass therefrom into the interior of the shell.Thus the lamp is supported -from the insulating sleeve by means of theconducting wires which uconvey the electricity to the lamp. In order toprevent chaling of the wires and to prevent cutting through theinsulating covering thereof, the wall of the chamber slopes at 13 towardthe shell so that a smooth surface is provided to contact with thewires. The sloping portion 13 may be formed integral with the head ormay be a separate ring of insulating material placed within the chamberafter the sleeve has been made.

The resilient means 3 for supporting the insulating sleeve is preferablya helical spring surrounding the shell. In order to provide bearingpoints for the spring, the head is formed to present a shoulder 14: onits lower side and av flange 15 projects inwardly from the wall of theaperture 8 near the lower end of the boss forming a reduced orifice. Theshell 9 is of a size to permit its passing through the orifice toprevent the wires 5 from rubbing against the sides of the orifice as thesleeve moves up and down to absorb vibration.

The boss is provided with openings 16 to permit the passage of the upperends of the wires 5 from the knot 12 to metallic contact plates 17 heldon the under side of the flange 6 by the usual screws 18. The contactplates are provided with the usual screws 19 for connecting the ends or"the wires 5 to the contact plate and screws 20 for connecting the linewires (not shown) to the contact plates. To permit the passage of thewires 5 from the knot 12 to the opening 16, a space 21 is provided inthe upper part of the rosette and to prevent chafing of the wiresagainst the upper part of the head 10 openings 22 are formed in the wallof the head so that when the sleeve moves the upper edge of said wallis. permitted to pass above the wires.

From the above description it will be seen that with the rosette shownit is un necessary to provide any fixture to support the lamp and thelamp is resiliently sup ported by the wires wnich convey the electricityfrom the line wires to the lamp. All the parts of the rosette are cheapand easy to manufacture. and the entire device is of extremely simpleconstruction and may be easily assembled. The rosette is designed totake the place of the usual non-resilient romtte from which electriclamps are now supported and therefore is preferably made to have suchproportions and have the openings, particularly the openings 7, sopositioned that the rosette may be used in the places from whichthenon-resilient rosettes are removed. The proportions of the device may bechanged and it is obvious that other modifications may be made and ittherefore, desired that the invention be construed as broadly as thelimitations in the claims, taken in conjunction with the prior art, mayallow.

Having thus described the invention what is claimed as new and desiredto be secured by Letters Patent is:

In an electric light fixture, the combination with an electric lamp of aceiling rosette comprising a depending apertured boss, a flangeprojecting inwardly from the wall of the aperture near the lower end ofthe boss forming a reduced orifice, an insulating sleeve within theaperture having an elongated shell formed of light material and ofuniform diameter to permit its passing through said orifice and anenlarged head forming a part of the shell and adapted to fit and morewithin the aperture, said head having a chamber communicating with theinterior of the shell and presenting a shoulder on its lower side, acoiled spring surrounding said shell and bearing at one end against theflange and at the other end against the shoulder resiliently to supportthe sleeve, and conducting wires for conveying electric current to thelamp, said wires being fastened to the lamp to support the lamp andtwisted to form a knot of a size to lie and be retained within thechamber of the head whereby the lamp is resiliently supported by thewires.

In testimony whereof. we have signed our names to this specification.
